An eroded volcanic core (similar to Glasshouse Mountains, Queensland) nestled within a deep valley.
Hike through rainforest and across two swinging bridges (think Indiana Jones) over a stream.
Hike down into the huge crater (11 km across) of an inactive volcano. The crater is mostly eroded. There are two gaps in the sides of the crater walls that water has eroded through over the centuries. The interior of the crater is sandy and desolate and contains many cinder cones (sand hills formed from smaller volcanic activity).
